Unspecified vulnerability in Oracle MySQL 5.5.46 and earlier, 5.6.27 and earlier, and 5.7.9 and MariaDB before 5.5.47, 10.0.x before 10.0.23, and 10.1.x before 10.1.10 allows local users to affect confidentiality, integrity, and availability via unknown vectors related to Client. NOTE: the previous information is from the January 2016 CPU. Oracle has not commented on third-party claims that these are multiple buffer overflows in the mysqlshow tool that allow remote database servers to have unspecified impact via a long table or database name.

Security readout for executives and security teams

CVE-2016-0546 affects older Oracle MySQL and MariaDB releases. The public record says a local user could affect confidentiality, integrity, and availability through an unspecified Client-related issue. Third-party reporting claimed mysqlshow buffer overflows involving long database or table names, but the bundle says Oracle did not confirm those details. Exposure is most likely where legacy MySQL or MariaDB client packages remain installed, especially on systems allowing local shell users or automated database tooling. The record also raises, but does not confirm, concern around clients interacting with hostile database names from a server. Treat this as a legacy exposure cleanup item unless affected clients are still widely deployed or used on shared systems. The business priority is reducing old database tooling with unclear impact, not responding to known active exploitation based on the supplied evidence. Mitigation focus: Upgrade Oracle MySQL beyond 5.5.46, 5.6.27, and 5.7.9 where applicable.; Upgrade MariaDB to at least 5.5.47, 10.0.23, or 10.1.10 as appropriate.; Apply vendor distribution updates from Oracle, MariaDB, Debian, Ubuntu, Red Hat, or SUSE..
